I moved the 3rd party app out of C:\Program Files and into a C:\TEMP folder.... everything is working as expected now. I don't really fault Windows virtualization feature, other than -- it would've been nice to get a dialog prompt from Windows, when I started SQLite from the command line, that said something like "unable to access the Data folder, using a virtualStore copy instead" or something. Poor SQLite (and I) had no idea it wasn't reading the "real" data file.
